Generate script source data in scenario when decompiling scripts.

[ShellyHerself]

Explanation I've gotten:
"You should have refinery decompile scripts and save it into the script source data block when extracting a scenario tag. Scenario tags without source data are undefined and can break when built with tool.exe again. For example reference a child scenario and compile it again, the scripts will now be gone because tool will try to recompile the scripts and see that there are no scripts because there is no source data."
